Our special gas globe valve adopts the lifting rotary rod type, the hand wheel and the valve stem are rotated and lifted together, and the nut is located on the valve body to prevent the valve stem from corrosion caused by external factors, which makes the hand wheel rotation not flexible and shorts the service life of the valve. An upper seal is added to the valve body structure. When the valve is in the open state, it works in conjunction with the packing to provide two layers of sealing effect and offers some protection for the packing. It has self-sealing performance and does not require manual maintenance.
● The use of elastic V-shaped polytetrafluoroethylene combined packing material ensures enhanced sealing performance as the medium pressure increases.
● The sealing surface of the valve body is processed after surfacing with stainless steel electrode.
● The opening torque is small and requires no manual maintenance.
